What is Gold CIP/CIL Processing Plant ?

Gold CIP/CIL Processing Plant

The gold cyanidation process, also known as gold CIL (Carbon in Leach) or CIP (Carbon in Pulp), is a hydrometallurgical technique used to extract gold from ore by converting the gold into a water-soluble coordination complex. This method is the most widely used leaching process for gold extraction, accounting for approximately 90% of global gold production.

DASEN MINING boasts 30 years of experience in producing gold CIL/CIP equipment and managing EPC (Engineering, Procurement, and Construction) projects. We have completed over 60 projects worldwide.

Gold Cyanidation Leaching Processing Flowsheet

Step 1： Pulp impurity removal
Before the adsorption of cyanide pulp, wood chips, and other impurities shall be treated to prevent gold and activated carbon in wood chips adsorption pulp from mixing into rich carbon and prevent wood chips from blocking the carbon-separation screen.
Step 2 :Leaching and adsorption
Add activated carbon into the leaching tank. The activated carbon adsorbs the gold in the pulp to become gold-loaded carbon. After adsorption, the activated carbon and pulp are separated by a carbon extraction sieve.
Step 3 :Desorption electrolysis
Gold-loaded carbon can be rapidly desorbed and electrolyzed into gold mud and lean carbon under the conditions of high temperature and high pressure in a closed system.
Step 4:Smelt
After simple pickling and removal of impurities, the obtained gold mud can directly smelt gold ingots.

Q&A

Does the gold particle size influence the leaching?
The size of gold particles significantly impacts the cyanidation process. Coarse gold particles (greater than 74 micrometers) dissolve slowly, making gravity separation or flotation methods preferable for recovering these particles before cyanide leaching. Additionally, ensuring the complete monomer dissociation of fine gold particles during grinding is crucial for enhancing the gold leaching rate.
How about the pulp pH value?
In practice, maintaining the pulp pH value between 10.0 and 11.0 is crucial. The cyanide leaching rate of gold ore decreases if the pH value exceeds 12 due to excessive alkalinity or falls below 9 due to insufficient alkalinity. To mitigate the hydrolysis of cyanide and reduce the volatilization of toxic HCN, lime can be added. Additionally, lime neutralizes acidic substances and precipitates harmful ions in the pulp, creating optimal conditions for gold dissolution.
What is the pulp density of the leaching process?
The diffusion rate of cyanide and oxygen in pulp is directly influenced by the pulp concentration. Excessive concentration hinders gold cyanide leaching. Therefore, determining the optimal pulp concentration through mineral processing tests is essential. For gold ore with minimal mud and impurities, high-concentration leaching, typically controlled at 40%-50%, is suitable. Conversely, for gold ores with complex mineral compositions and high mud content, low-concentration leaching, usually around 25%, is recommended.
What is the range of leaching temperature?
The cyanide leaching of gold accelerates with increasing temperature due to heightened ion activity. However, as temperature rises, the amount of dissolved oxygen significantly decreases, reaching zero at 100°C, which makes leaching impossible. Additionally, higher temperatures increase the self-hydrolysis of cyanide and accelerate the cyanide reaction with base metals, leading to higher cyanide consumption and reduced solubility of Ca(OH)₂, resulting in a lower pulp pH value. Generally, cyanide leaching does not require heating, and the temperature should be maintained between 15-30°C.
How about the leaching time?
The cyanidation leaching time depends on the material properties, cyanidation method, and conditions. Generally, agitation cyanidation leaching lasts more than 24 hours, sometimes extending to 40 hours, while gold telluride cyanidation requires 72 hours. Percolation cyanide leaching, on the other hand, takes more than 5 days.

Since no two mines are identical, varying ore and concentrator conditions necessitate different gold cyanide leaching methods and technical parameters. Therefore, it is recommended to conduct a mineral processing test first. Based on the test results, the optimal conditions for the gold cyanide leaching process can be determined to achieve ideal technical and economic outcomes.
